i've got a question to ask regarding the nagios on ubuntu 10.4
i have managed to create the nagios interface etc, and when i viewed the service status, the SSH service has a CRITICAL status.
how do i resolve that? thanks
Do you have ssh installed?
If not, do the following on the command line
apt-get install openssh-server openssh-client
Then reschedule the SSH check and see if it returns "OK"
